    I might be wrong, but 13,500 sounds kind of low with a 6 x 3 and open exhaust.
    I do not understand why the Cox engine needs so much exhaust port area compared to an AME .049 [for example]. I guess...

    What I do is shape the foam, then cover it with clear packing tape to act as the release membrane. After the FG cures dig into the foam with a wood chisel the...
